Minelab E-Trac Classroom Forum

I do the 90 degrees and also switch to Quickmask like most of the above but am working to understand the TTF

Take my advice on this one because I do not have a clue on what everybody is talking about, but I did go out with my new Etrac today and figured out how to turn it on. This was my first time out so I thought I would begin to learn my Etrac but as someone here suggested I did a search for TTF and loaded those settings. Hit the school yard and BAM 1 silver quarter, 3 silver dimes, 1 SILVER RING that fits perfect, 4 clad quarters, I think 3 dimes, and 5 or 6 pennies, clad I dropped in piggy bank only 1 bad dig piece of foil. Good or bad, did not learn a dam thing except my Etrac works. Search TTF

Yes I have Trash - High and Ground - difficult on. I did modify the basic coin program based on suggestions from an E-Trac user. Here are the settings.

sensitivity auto +3
threshold limit just barely audible
volume limit 29
volume gain 29
response normal
tone id multi
sounds conductive
variability 29
limits 29
threshold pitch 28-29
deep off
fast on
trash high
ground difficult

Gain set too high for conditions/area you were hunting......=Iron Falsing.........

Having your gain set too high will cause iron falsing? I never thought about that. Will back the gain off to about 20 and see how that works.

Yes, it is probably the number one user induced cause of falsing imo. I say "user induced" as when the ground is wet it happens even more (in my ground.)
Just drop your auto+3 down until the falsing seems to go away. I guess you could test this on target you come across in the field to keep the depth optimal.

I run manual even with the falsing. As you learn the unit better the falses stand out more, though I still dig deeper iron nails on occasion, but also pull deeper coins in iron ;-)

Also try lowering your THRESHOLD PITCH to factory 15 or 20 so all coins won't be as high a pitch sound especially the real high conductors so now you can possiably hear a difference in the pitch of the sound from a clad to a silver to iron as they each will sound a bit different. If you set Threshold Pitch range up to where you have it at (28-29) all the targets sound way more sceetchy and therange of sound is compressed to the upper end. I even went lower for my range of hearing like 5 on down to 1 on the threshold pitch scale and it made a BIG difference in my being able to distinguish the difference in the sounds of all the different targets I encounter. It spreads the sound range out more on the targets to me so they weren't all so high pitched screetchy to my ears which made it hurt after a while.

Try another Pro coil, or other, or go to older Explorer, Etracs more in tune with Iron, and for experienced users its not bad.

I use the wide open quick mask all the time on those iffy signals. Saves alot of time not digging the junk, but if it is still jumpy in quick mask and I still get some good numbers along with cursor position I will dig it and have found some silver doing that.

Technically Vol Gain has little effect on iron falsing. It neither makes the detector less or more sensitive to targets. However, running lower Vol Gain will keep the audio cleaner, that is, the audio can be too extreme making the separation between weak and strong targets indiscernable.

If iron falsing is occurring turn down the +3 Auto Sens until it disappears, perhaps -2 Auto. You aren't going to lose much depth since iron spreads out the EM signal and does a tremendous job of decreasing depth on its own right. So, go ahead and reduce the sensitivity.

Overpowering the nail head and nail tip with circulating eddies will give those high chirps that sound somewhat like non-ferrous coins. Normally an iron nail is all reactive signal and is easily disc'd out by detectors. But when they are bent or have sharp edges the resistive signal can impersonate the non-ferrous target.

Also, turn Trash Density to High - it will help lock on the good accepted signal letting it through and block out the less consistent signals.
